Recompiling All PL/SQL Modules

Run the utlrp.sql script after you install, patch, or upgrade a database, to identify and recompile invalid PL/SQL modules.

The utlrp.sql script recompiles all PL/SQL modules, including packages, procedures, and types. Recompiling the modules corrects any invalid objects created during installation.

(Optional) Enter task prerequisites here.

Log in as the oracle user.
Use the oraenv or coraenv script to set the environment for the database where you want to run the utlrp.sql script:
- Bourne, Bash, or Korn shell:
```
$ . /usr/local/bin/oraenv
```
- C shell:
```
% source /usr/local/bin/coraenv
```
When prompted, provide the system identifier (SID) for the database.
Start SQL*Plus as SYSDBA.
For example:
```
$ sqlplus / AS SYSDBA
```
Start the database in restricted mode and run the utlrp.sql script.
For example:
```
SQL> STARTUP RESTRICT
SQL> @$ORACLE_HOME/rdbms/admin/utlrp.sql
```
